Billie Eilish, 19, made a striƙing impression as she co-hosted the 2021 Met Gala, themed ‘In America: A Lexicon of Fashion,’ on Sept. 13. Initially gracing the red carpet in an elegant gown reminiscent of Marilyn Monroe, she later transformed her look for the after-party.

 Opting for a bold choice, Billie wore a black leather pleated mini dress with a sheer black lace short-sleeve overlay. She paired this edgy ensemble with black leather mid-calf combat boots, showcasing a stark contrast to her earlier glamorous appearance.

Billie’s two outfits from the evening showcased her vеrsatility. The gala entrance featured a stunning pale peach Oscar de la Renta gown with an off-the-shoulder neckline and a flowing train that elegantly covered the steps. 

This departure from her usual grungy style surprised many, affirming her ability to embody diverse looks that align with the event’s theme.

It was Billie’s inaugural Met Gala, and she successfully embraced both styles with confidence. Just weeks prior, she had revealed a new haircut on social media, opting for a shorter, shaggier look below her jawline with front bangs. This change marked a departure from her previous shoulder-length blond hair with layers and front bangs. However, for the gala, Billie’s hair appeared longer, styled in voluminous old-Hollywood waves to complement the evening’s theme.
